Thisinvention relates to a feed water heater for'locomotives. Tlie bject 'Qf tllef invention'is to parallel the temperatures of the Water in the boiler of a locomotive and that of the feed-Water:suppliedthereto.

In carrying out my invention; I 'mount on heated steam drawn fromzthe boiler-from'a superheat headerand led into'the drum at the front end and Withdrawn therefrom by I a pipe terminating atj-itsr opposite end and f a T Figure 1 represents in'ele'vationf'a'locomo-c tive boiler contalmng my improvements; afeed Water 1 end of the heater or drum;
